To echo Centered's question, is it okay to spray outside on a breeze-less day without a booth but using a respirator? Or perhaps using a box to contain the overspray, and wearing a respirator, but without an exhaust fan on the box? I want to spray glazes but don't have room for a spray booth. I like the idea of a deep sink turned on its side, as then I could wash the overspray out the drain hole and into a bucket. I am not crazy about the idea of nothing to contain overspray, as we have a lot of wildlife and a dog who are often outside the studio.

I spray my salt pots outside with slips and a little glaze-wear a mask .
I set up a stool with a banding wheel-hose it all down when done.
I do this very infrequently.If I sprayed a lot I would build a booth with a large 10 inch fan.

I took apart my spray booth and started spraying outside. Obviously, there are disadvantages, but for me the advantages over an indoor spray booth far outweigh the disadvantages. I'm in Georgia, so winter isn't as cold or long as other places but I have sprayed outside when the temp was in the 20's and it wasn't that bad.
